The laws pertaining to shehitah, Jewish ritual slaughter, are explored. The laws derive from the oral law, stemming from the prohibition to eat the flesh of live animals, in combination with the general Biblical obligation for humane treatment of animals. The first part of this paper is an exposition of the origins of shehitah, and the laws for correctly carrying out the process. The second part of this paper addresses the history of the practice of these laws in select European countries and the United States. This history includes a discussion of anti-shehitah campaigns and legislation through modern times.
